A “chipper” is a longer workout, typically one round for time, that you just “chip away” at. Some say it’s a workout that, at the end, makes you feel like you feel like you were fed through a chipper. This is a scaled-down version of a mainsite chipper:

On each team, only one person can be doing these reps at a time, and their reps only count while the other three team members are doing the following: 1) bottom-to-bottom air squats, rep for rep (rest at bottom); 2) hollow body hold; 3) holding a plate overhead (45/25). Team members can switch out however they want, but again, the reps only count while all three of the other things are happening.
At end, team must run as a group from the field house to the road between the field house and the soccer field and back, with two team members carrying a third by the hands and ankles, like a stretcher. Swap out as necessary.

If you’re really ambitious, you can do Angie, which is 100 reps of each exercise. Either way the WOD is to complete all reps on each exercise before moving to the next one. Scale as needed (e.g. jumping pull-ups, push-ups on a box)
